The blocking device comprises a fixed plate 10 and plates 13, 14, which are reciprocable relative to the plate 10. A table 5 is arranged between the input conveyers 2, 3, and the intermediate conveyer 7, in the centre of which is mounted, the fixed plate 10. Control means is provided with feelers 17, 18, which are arranged upstream of the blocking devices so that they are pivoted by incoming articles. Delay means (not shown) are provided for enabling the blocking devices to be actuated only when the duration of the pivoting of the feelers exceeds a predetermined interval of retardation. Feelers 21 and 22 prevent operation of the associated blocking device when an article is in a position (e.g. 1<SP>5</SP>) in which the article might be badly orientated by the action of the blocking devices. Instead of the clamp type blocking devices shown, stops may be used. There may be more than two input streams,

Abstract: 1,206,348. Depth gauges. BIOSGESELLSCHAFT HERMANN BITTER. Dec.3, 1968 [Dec.7, 1967], No.57283/68. Heading G1M. A method of detecting and marking a selected undercut depth of teeth in the course of manufacture of denture clasps is characterized in that after detecting the selected undercut depth using a probe 12, the location of the selected depth is marked by the probe. The probe is mounted on a device 4 which is secured in a vertical attitude by a pin 5. The device is moved around a tooth 1 held in a jaw model 2 so that the point of engagement of a pin 13 with the tooth follows a line 3 representing the maximum profile of the tooth. A pointer 6 biased by a spring 7 is connected to a cam 8 operated by a plunger 9. The plunger 9 is operated by a member 11 pivoted at 10, the probe 12 being attached to the member. The probe consists of a resistance wire having leads 13a, 14 and when the dial indicates that the probe has detected the points having the pre-selected undercut depth, current to the resistance wire is switched on thus causing the probe to mark a coating applied to the tooth. In a modification, the marking is effected by a pin which is manually pivoted into engagement with the tooth.
